A CORPORATION yO1? CONNECTICUT senr L'ooirruesinne LOOP Application filed .Ilecember 29, 1930.

The object of this invention is to provide a metallic loop which when applied to an article, such as a suspender end or strap like those used, for example, on overalls, may be adjusted on such suspender or strap to properly connect with another object, such as la button or loop on the waistband of a garment, to obtain the proper elevation of the garment, or its fit on the wearer, the loop being locked by its own mechanism in given working position.

In two copending applications, there are shown self-locking slide loops of the general character above described, and in which the swinging locking member is made of wire and applied to the body of the loop at its front. As one distinguishing feature of the present invention, it is noted that the locking member is of sheet metal and located at the back of the body of the loop.

The invention herein consists of a selflocking slide loop having a body of wire provided with a cross bar at its upper portion, the ends of this cross bar being bent downwardly and turned inwardly toward each other substantially parallel with the upper portion, and to which turned-in ends a sheet metal swinging locking bar is pivoted or hinged and extends upwardly at the rear of the loop, said locking bar having a transverse slot which in cooperation with the upper cross bar of the body serves to lock the loop in adjusted position on a suspender end or strap, as will now be explained and finally claimed.

In the accompanying drawing illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1 is a front elevation and Fig. 2 a side elevation of the self-locking slide loop mounted upon a suspender or strap end. Fig. 3 is a perspective view of the device detached.

The invention is shown as applied to a well known form of button loop made of wire, such as shown in the Howe patent, No. 961,718, granted June 14, 1910, but the invention is susceptible of use on other forms of loop.

The wire loop shown comprises the upper cross bar 1, having the downwardly extended and inwardly turned portions 2, from which Serial No. 505,419.

depend the springy or elastic limbs 3 which terminate in eyes 4 in which is suspended a button-engaging loop 5, all substantially as in the Howe patent above referred to.

Instead of applying a swinging bar or locking device made of wire as in the applications above referred to, the swinging bar or locking device of this present invention is made of a piece of sheet metal, indicated at 6, which is provided with a transverse slot 7, and has the knuckles 8 which are connected with the members 2, 2, which together constitute hinges and on which the part 6 swings. The relative position of the part V6 is on the back of the wire member, and the slot 7 and the cross bar 1 are substantially opposite and are always so in use, s0 that by making part G of sheet metal and consequently thin, the suspender or strap makes a shorter or quicker turn and therefore the holding of the suspender or strap is secure.

By making the swinging member or bar of sheet metal, the edges of the slot 7 enhance the gripping or grasping qualities of the device when applied to a suspender or strap.

The suspender or strap 9, as shown in Figs. 1 and 2, is first passed through the slot 7 in the bar G from back to front and at the front its extends over the top of the upper cross bar 1 and is then returned backwardly beneath the said cross bar and out through the slot 7, where its free end 9 falls down behind the loop and thus serves as a guard or protector against contact of the loop with the body or wearing apparel of the user.

As is evident from Fig. 2, the lengthwise strain on the strap is resisted by the double action of the edge of the slot 7 and the cross bar 1.

In the present invention the bight put in the suspender or strap and connecting it with the loop is located on the upper cross bar of the loop itself instead of the swinging bar. Thus when strain is put upon the suspender or strap, the reaction of the swinging bar as it crowds towards the loop is to strengthen the grip orgrasp on the suspender or strap.

The use of a sheet metal swinging bar provides space for advertising and trademark purposes.

Variations in the details of construction are permissible within the principle of the invention and the claims following.

What is claimed is 1. A self-locking slide loop, having a wire body provided with a transverse upper cross bar and a swinging bar of sheet metal pivoted to the body below its upper cross bar and provided with a transverse slot, and a suspender or strap looped about the cross bar and through the swinging bar, the edges of the slot in the swinging bar engaging both sides of the suspender or strap back of the bight in the suspender or strap.

2. A self-locking slide loop, having a Wire body provided with a transverse upper cross bar and a swinging bar of sheet metal pivoted to the body below its upper cross bar and provided with a transverse slot, said swinging bar arranged at the back of the body, and a suspender or strap looped about the cross bar and through the swinging bar, the edges of the slot in the swinging bar engaging both sides of the suspender or strap back of the bight in the suspender or strap.

1n testimony whereof I have hereunto set my hand this 23rd day of September, 1980.
